Scale for winds in the open air (8)

Ross

I believe the answer is:

alfresco

'in the open air' is the definition.
(I've seen this before)

'scale for winds' is the wordplay.
'winds' indicates an anagram.
'scale'+'for'='scalefor'
'scalefor' is an anagram of 'ALFRESCO'.

(Other definitions for alfresco that I've seen before include "Meal eaten in the outdoors" , "Outdoors, meal perhaps" , "In the open air" , "out of the house" , "Open-air" .)

I've seen this clue in The Sun.
